Description

本発明は、昇降物干し装置に関するものである。   The present invention relates to a lift / drying apparatus.

従来から、図６（ａ）のように、天井に配設されて駆動部３にて回転駆動される巻取りドラム４を有する本体部２と、本体部２からワイヤ５にて吊持されてワイヤ５の巻取りドラム４への巻取り・巻戻しに応じて昇降される物干し竿６とを備えた昇降物干し装置１が知られている（たとえば特許文献１参照）。   Conventionally, as shown in FIG. 6A, a main body 2 having a winding drum 4 disposed on a ceiling and driven to rotate by a drive unit 3, and a wire 5 is suspended from the main body 2. 2. Description of the Related Art A lifting / drying apparatus 1 is known that includes a clothes rack 6 that is lifted / lowered in accordance with winding / rewinding of a wire 5 to / from a winding drum 4 (see, for example, Patent Document 1).

この昇降物干し装置１は、物干し竿６を下降させて使用者に洗濯物を引っ掛けさせたり、上昇させて天井近傍で洗濯物を干したりして使用されるのであるが、このような物干し竿６の昇降制御を行わせるための物干し竿６の昇降位置の検出手段（竿位置検出手段１０）としては、たとえば図６（ｂ）のものが採用されている。   The lifting / drying apparatus 1 is used by lowering the hanging basket 6 to make the user hook the laundry, or raising the hanging basket 6 to dry the laundry in the vicinity of the ceiling. For example, the lifting / lowering position detection means (the heel position detection means 10) of the hanging basket 6 is used as shown in FIG. 6B.

この竿位置検出手段１０は、駆動部３に回転自在に設けた検知ディスク３０と、検知ディスク３０に設けた回転により電気的に抵抗値が変化するポテンショメータのような可変抵抗３１とを有して構成されている。詳しくは、検知ディスク３０は巻取りドラム４を減速回転させる駆動部３の伝達動力の一部を抽出して巻取りドラム４の回転に同期して減速回転するように設置されており、巻取りドラム４の回転量と同期する検知ディスク３０の回転量により変化する可変抵抗３１の抵抗値を見ることで巻取りドラム４へのワイヤ５の巻取り量を検知し、物干し竿６の昇降位置の検出を行わせている。   The saddle position detecting means 10 includes a detection disk 30 that is rotatably provided in the drive unit 3 and a variable resistor 31 such as a potentiometer whose resistance value is electrically changed by rotation provided in the detection disk 30. It is configured. Specifically, the detection disk 30 is installed so as to extract a part of the transmission power of the drive unit 3 that decelerates and rotates the take-up drum 4 and to decelerate and rotate in synchronization with the rotation of the take-up drum 4. The amount of winding of the wire 5 around the winding drum 4 is detected by observing the resistance value of the variable resistor 31 that changes depending on the amount of rotation of the detection disk 30 synchronized with the amount of rotation of the drum 4, and Detection is performed.

しかしながら、この竿位置検出手段１０における検知ディスク３０の回転量は、駆動部３の巻取りドラム４への伝達動力に基づくものであって、巻取りドラム４の実際の回転量に基づくものではない。つまり、この竿位置検出手段１０で検出される物干し竿６の昇降位置は、巻取りドラム４の回転量（ワイヤ５の巻取り量）に間接的に同期したものとなっている。しかして、駆動部３に伝達ロスなどが生じたりすると、検知ディスク３０と巻取りドラム４との同期性が失われ、物干し竿６の昇降位置の正確な検出、ひいては正確な物干し竿６の昇降制御ができなくなるという問題があった。   However, the amount of rotation of the detection disk 30 in the saddle position detection means 10 is based on the power transmitted to the winding drum 4 of the drive unit 3 and is not based on the actual amount of rotation of the winding drum 4. . That is, the lifting position of the hanging basket 6 detected by the basket position detecting means 10 is indirectly synchronized with the amount of rotation of the winding drum 4 (the amount of winding of the wire 5). If a transmission loss or the like occurs in the drive unit 3, the synchronization between the detection disk 30 and the take-up drum 4 is lost, and accurate detection of the lifting position of the hanging basket 6 is performed. There was a problem that it was impossible to control.

更に言うと、ポテンショメータのような可変抵抗３１を備える検知ディスク３０は、複数回転する巻取りドラム４に対して１回転に満たない回転運動をするように、駆動部３にディスク用減速機構を介して設置されるものであるが、このディスク用減速機構により竿位置検出手段１０が複雑化してしまうのであり、また、図５（ｂ）のディスク用減速機構は駆動部３の駆動モータの出力軸に設けたピニオン３２に検知ディスク３０の外周に刻設した歯車部が噛合して構成されているが、充分な減速比を得るためには検知ディスク３０の歯車部の歯数を増加、ひいてはその外径を大きく形成しなければならず、竿位置検出手段１０が昇降物干し装置１の小型化を阻害することにもなっていた。
特開２０００−１２６４９７号公報 More specifically, the detection disk 30 having a variable resistor 31 such as a potentiometer has a disk speed reduction mechanism in the drive unit 3 so as to rotate less than one rotation with respect to the winding drum 4 that rotates a plurality of times. However, this disc speed reduction mechanism complicates the saddle position detection means 10, and the disc speed reduction mechanism shown in FIG. 5B is an output shaft of the drive motor of the drive unit 3. In order to obtain a sufficient reduction ratio, the number of teeth of the gear portion of the detection disk 30 is increased, and as a result, the pinion 32 provided on The outer diameter has to be formed large, and the heel position detecting means 10 has also hindered downsizing of the lifting / lowering clothes drying apparatus 1.
JP 2000-126497 A

In addition, an object of the present invention is to provide a lifting / drying apparatus capable of ensuring the simplicity of the structure of the heel position detecting means and reducing the size of the apparatus.

上記課題を解決するために請求項１に係る昇降物干し装置にあっては、天井に配設されて駆動部３にて回転駆動される巻取りドラム４を有する本体部２と、本体部２からワイヤ５にて吊持されてワイヤ５の巻取りドラム４への巻取り・巻戻しに応じて昇降される物干し竿６とを備えた昇降物干し装置１であって、巻取りドラム４と一体回転するように検知胴部７を設けると共に、この検知胴部７の外周に螺旋溝８を刻設し、本体部２に設置した直線摺動自在なスライド突起９を螺旋溝８に係入し、巻取りドラム４の回転に応じた螺旋溝８の規制にて決定されるスライド突起９の摺動位置を検知して物干し竿６の昇降位置を検出する竿位置検出手段１０を設けたことを特徴とする。   In order to solve the above-described problem, in the lifting / drying apparatus according to claim 1, the main body 2 having the winding drum 4 disposed on the ceiling and driven to rotate by the driving unit 3, and the main body 2. A lifting / drying apparatus 1 provided with a hanging basket 6 that is suspended by a wire 5 and lifted / lowered in response to winding / rewinding of the wire 5 to / from the winding drum 4, and rotates integrally with the winding drum 4. In addition to providing the detection body 7, a spiral groove 8 is engraved on the outer periphery of the detection body 7, and a linearly slidable slide protrusion 9 installed on the main body 2 is engaged with the spiral groove 8. A heel position detecting means 10 for detecting the sliding position of the slide protrusion 9 determined by the restriction of the spiral groove 8 according to the rotation of the winding drum 4 and detecting the raising / lowering position of the hanging basket 6 is provided. And

これによると、巻取りドラム４と一体回転するように設けた検知胴部７の外周に螺旋溝８を刻設し、本体部２に設置した直線摺動自在なスライド突起９を螺旋溝８に係入することで、巻取りドラム４の回転量を直接スライド突起９の同期した摺動量として抽出できる。そして、竿位置検出手段１０によってこのスライド突起９の摺動位置を検知して物干し竿６の昇降位置を検出したことで、巻取りドラム４の回転量（ワイヤ５の巻取り量）と直接的に同期した正確な物干し竿６の昇降位置の検出を確保できる。また、このように物干し竿６の昇降位置を正確に検知する構造は、巻取りドラム４と一体回転するように設けた検知胴部７の外周に螺旋溝８を刻設し、螺旋溝８に係入したスライド突起９を本体部２に直線摺動自在に設置するといった簡単な構造であり、つまり簡易な構造を確保して装置の小型化を図ることができる。   According to this, the spiral groove 8 is formed on the outer periphery of the detection barrel portion 7 provided so as to rotate integrally with the winding drum 4, and the linearly slidable slide protrusion 9 installed in the main body portion 2 is formed in the spiral groove 8. By engaging, the rotation amount of the winding drum 4 can be directly extracted as the synchronized sliding amount of the slide protrusion 9. Then, the sliding position of the slide protrusion 9 is detected by the saddle position detecting means 10 to detect the raising / lowering position of the hanging basket 6, so that the rotation amount of the winding drum 4 (the winding amount of the wire 5) is directly detected. It is possible to ensure the accurate detection of the raising / lowering position of the laundry basket 6 synchronized with the above. In addition, the structure for accurately detecting the raising / lowering position of the hanging basket 6 in this way has a spiral groove 8 engraved on the outer periphery of the detection barrel portion 7 provided so as to rotate integrally with the winding drum 4. It is a simple structure in which the engaged slide projection 9 is installed on the main body 2 so as to be linearly slidable, that is, a simple structure can be secured and the apparatus can be downsized.

また、請求項２に係る昇降物干し装置にあっては、請求項１において、竿位置検出手段１０が、スライド突起９の摺動位置にて抵抗値が変化する可変抵抗１１を有して成ることを特徴とする。   Further, in the lifting / drying apparatus according to claim 2, in claim 1, the heel position detection means 10 includes the variable resistor 11 whose resistance value changes at the sliding position of the slide protrusion 9. It is characterized by.

これによると、可変抵抗１１の抵抗値の増減によりスライド突起９の摺動位置、ひいては物干し竿６の昇降位置を電気的に検知できるのであり、物干し竿６の昇降制御を電気回路にて簡単に行わせることができる。   According to this, the sliding position of the slide protrusion 9 and consequently the raising / lowering position of the hanging basket 6 can be electrically detected by increasing / decreasing the resistance value of the variable resistor 11, and the raising / lowering control of the hanging basket 6 can be easily performed by an electric circuit. Can be done.

また、請求項３に係る昇降物干し装置にあっては、請求項１又は２において、検知胴部７を巻取りドラム４の同軸上に設けたことを特徴とする。   The lifting / lowering apparatus according to claim 3 is characterized in that, in claim 1 or 2, the detection body 7 is provided coaxially with the winding drum 4.

Can do.

本発明にあっては、竿位置検出手段が巻取りドラムの回転量を直接検知して物干し竿の昇降位置の正確な検出を可能にすると共に、この竿位置検出手段の構造の簡易性を確保して昇降物干し装置の小型化を図り得る、という利点を有する。   In the present invention, the saddle position detection means directly detects the amount of rotation of the winding drum to enable accurate detection of the lifting position of the clothesline, and ensures the simplicity of the structure of the saddle position detection means. Thus, there is an advantage that the elevator / drying apparatus can be miniaturized.

以下、本発明を添付図面に示す実施形態に基いて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

本例の昇降物干し装置１は、図１（ａ）のように天井に配設される本体部２と、本体部２からワイヤ５にて吊持される物干し竿６とを備えている。物干し竿６は、本体部２に備えた駆動部３にて回転駆動される巻取りドラム４に対してワイヤ５を巻取り・巻戻しさせることで、昇降駆動される。昇降物干し装置１は、制御部１５の物干し竿６の昇降制御によって、物干し竿６を下降させて使用者が洗濯物を引っ掛け、物干し竿６を上昇させて天井近傍で上記洗濯物を干すといったように使用されるのであるが、本例では図１（ｂ）のように、物干し竿６の昇降制御の正確性を確保すると共に構造の簡易性も確保して装置の小型化に資することのできる竿位置検出手段１０を備えたことに特徴を有している。以下、詳述する。   The elevator / drying apparatus 1 of the present example includes a main body 2 disposed on the ceiling as shown in FIG. 1A and a laundry basket 6 suspended from the main body 2 by a wire 5. The laundry basket 6 is driven up and down by winding and rewinding the wire 5 with respect to the winding drum 4 that is rotationally driven by the driving unit 3 provided in the main body unit 2. The elevator / drying apparatus 1 is configured such that, by the lifting / lowering control of the hanging basket 6 of the control unit 15, the hanging basket 6 is lowered, the user hooks the laundry, the lifting basket 6 is lifted, and the laundry is dried near the ceiling. In this example, as shown in FIG. 1 (b), it is possible to ensure the accuracy of lifting control of the hanging basket 6 and also to ensure the simplicity of the structure, thereby contributing to the downsizing of the apparatus. It has a feature in that it includes the heel position detecting means 10. Details will be described below.

本体部２は、図１（ａ）のように、物干し竿６の長さ方向に長尺に形成されており、具体的には、天井に取り付ける板状の本体ハウジング１３と、本体ハウジング１３の下方を覆うように被着される本体カバー１４とで構成される。本体ハウジング１３には、駆動モータ１７を有した駆動部３や、駆動部３にて回転駆動される巻取りドラム４や、駆動部３の動作制御をする制御部１５が装着される。巻取りドラム４は本体ハウジング１３の長手方向の両端部にそれぞれ配置されており、物干し竿６の長さ方向の両端を吊持する一対のワイヤ５を対応する各巻取りドラム４に巻装可能にしている。   As shown in FIG. 1 (a), the main body 2 is formed in an elongated shape in the length direction of the clothes basket 6, and specifically, a plate-shaped main housing 13 attached to the ceiling, The main body cover 14 is attached so as to cover the lower part. A drive unit 3 having a drive motor 17, a winding drum 4 that is rotationally driven by the drive unit 3, and a control unit 15 that controls the operation of the drive unit 3 are mounted on the main body housing 13. The winding drums 4 are arranged at both ends in the longitudinal direction of the main body housing 13 so that a pair of wires 5 that suspends both ends in the length direction of the clothes basket 6 can be wound around the corresponding winding drums 4. ing.

この一対の巻取りドラム４は両者に架設した連結軸棒１６により一体化されると共に、一方の巻取りドラム４が駆動部３の出力軸３ａに取り付けられていて、駆動部３の回転駆動により連結軸棒１６を介して一対の巻取りドラム４が一体に回転駆動するようになっている。つまり、駆動部３は本体ハウジング１３の長手方向の一端部に配置されていて、駆動モータ１７の出力回転を減速させて巻取りドラム４に出力するギアボックス１８を備えている。このギアボックス１８には、たとえば図２のように、駆動モータ１７の出力軸１７ａに取り付けたウォームギア１９を一段目にして以下複数の平歯車２０を列設させて成る減速歯車列２１をケース２２で内装したものが採用できる。一段目の減速にウォームギア１９を用いて大きく減速すると共に、この減速歯車列２１をケース２２にて覆うことで静音化が図られており、好ましい。   The pair of winding drums 4 are integrated by a connecting shaft rod 16 installed on both of them, and one winding drum 4 is attached to the output shaft 3 a of the drive unit 3. A pair of winding drums 4 is integrally rotated through a connecting shaft rod 16. That is, the drive unit 3 includes a gear box 18 that is disposed at one end portion in the longitudinal direction of the main body housing 13 and decelerates the output rotation of the drive motor 17 and outputs it to the winding drum 4. In this gear box 18, as shown in FIG. 2, for example, a reduction gear train 21 formed by arranging a plurality of spur gears 20 in a first stage with a worm gear 19 attached to the output shaft 17 a of the drive motor 17 is arranged in a case 22. Can be used for interior decoration. It is preferable that the worm gear 19 is used for the first stage of deceleration, and that the reduction gear train 21 is covered with a case 22 to reduce noise.

本体カバー１４には下方に開口する凹所状の竿収容部２３が凹設されており、上端位置にまで上昇した物干し竿６を竿収容部２３内に収容可能にしている。この本体カバー１４は本体ハウジング１３を下方から覆うように被着されるが、駆動部３や巻取りドラム４やその連結軸棒１６や制御部１５は竿収容部２３を囲うように（つまり平面視で各部位が重ならないように）本体ハウジング１３の下面に配置されており、本体部２内の無駄なスペースを極力無くして、本体部２、ひいては昇降物干し装置１の薄型化を図っている。詳しくは、従来技術の例の図６の昇降物干し装置１における本体部２は竿収容部２３の上方位置に重ねるように駆動部３や巻取りドラム４が配置された構成となっており、これに比べて本例の昇降物干し装置１が薄型化されているのは明らかである。なお、図中２４は制御部１５に接続した受信部が臨む本体カバー１４に設けた透光窓であり、使用者が操作するリモコン操作器の送信信号を受信部で受けて、リモコン操作器による物干し竿６の昇降操作を可能にしている。   The main body cover 14 is provided with a recessed bowl housing portion 23 that opens downward, so that the clothes basket 6 raised to the upper end position can be housed in the bowl housing portion 23. The main body cover 14 is attached so as to cover the main body housing 13 from below, but the drive unit 3, the winding drum 4, its connecting shaft rod 16, and the control unit 15 surround the bag receiving unit 23 (that is, a plane surface). It is arranged on the lower surface of the main body housing 13 (so that the respective parts do not overlap with each other in view), and the main body 2 and, consequently, the lifting / lowering object drying apparatus 1 are reduced in thickness by minimizing useless space in the main body 2. . Specifically, the main body 2 in the lifting / lowering apparatus 1 shown in FIG. 6 of the prior art example has a configuration in which the driving unit 3 and the winding drum 4 are arranged so as to overlap the upper position of the basket housing unit 23. It is clear that the elevator / drying apparatus 1 of this example is thinner than the above. In the figure, reference numeral 24 denotes a translucent window provided on the main body cover 14 facing the receiving unit connected to the control unit 15. The transmitting unit receives a transmission signal of the remote controller operated by the user at the receiving unit, and The lifting / lowering operation of the clothes rack 6 is made possible.

上記のように、巻取りドラム４は、平面視で物干し竿６に重なる位置（竿収容部２３）には配置されていないのであるが、図３のように、物干し竿６を吊持するワイヤ５は、本体ハウジング１３における竿収容部２３に重なる位置に回転自在に設けたプーリ２５を介して巻取りドラム４に巻装されるようになっている。なお、各巻取りドラム４は、その軸方向が本体ハウジング１３の長手方向に沿うように配置されて、両端にフランジ２６が設けられ、その間の外周面であるワイヤ巻取面２７にワイヤ５が巻装されるのであるが、このワイヤ巻取面２７は、本体ハウジング１３の中央側ほど外径が大になる傾斜面状に形成されており、つまり、ワイヤ５は、ワイヤ巻取面２７に本体ハウジング１３の端部側から順に並んで巻き付くように安定して巻装可能にされている（いわゆる整列巻きが可能にされている）。   As described above, the take-up drum 4 is not arranged at a position (the bag housing portion 23) that overlaps the clothes rack 6 in plan view, but the wire that holds the clothes rack 6 as shown in FIG. 5 is wound around the take-up drum 4 via a pulley 25 that is rotatably provided at a position overlapping the rod housing portion 23 in the main body housing 13. Each winding drum 4 is arranged such that its axial direction is along the longitudinal direction of the main body housing 13, flanges 26 are provided at both ends, and the wire 5 is wound around the wire winding surface 27 that is the outer peripheral surface therebetween. The wire winding surface 27 is formed in an inclined surface shape whose outer diameter increases toward the center side of the main body housing 13, that is, the wire 5 is formed on the wire winding surface 27 on the main body. The housing 13 is stably wound so as to be wound side by side in order from the end side (so-called aligned winding is possible).

ここで、少なくとも一方の巻取りドラム４には、図４のように、本体ハウジング１３の中央側においてその同軸上に検知胴部７が設けられている。検知胴部７は巻取りドラム４と一体に同軸回転されるのであり、検知胴部７の一定外径を有した外周面にはスラスト方向へ位置をずらすように螺旋を描く螺旋溝８が刻設されている。本例の場合、検知胴部７は連結軸棒１６の一端部に一体に形成されていて、連結軸棒１６を巻取りドラム４に固定したときに検知胴部７が一方の巻取りドラム４に隣接して配設されるようにしてある。   Here, as shown in FIG. 4, at least one winding drum 4 is provided with a detection body portion 7 on the same axis on the center side of the main body housing 13. The detection barrel 7 is coaxially rotated integrally with the winding drum 4, and a spiral groove 8 is formed on the outer peripheral surface of the detection barrel 7 having a constant outer diameter so as to shift the position in the thrust direction. It is installed. In the case of this example, the detection barrel 7 is formed integrally with one end of the connecting shaft rod 16, and when the connecting shaft 16 is fixed to the winding drum 4, the detection barrel 7 is one winding drum 4. It is made to arrange | position adjacent to.

そして、検知胴部７に重なる本体ハウジング１３の位置には、図１（ｂ）のように、物干し竿６の昇降位置を検出するための検知センサ１２が配設されている。本例の検知センサ１２は、直線的に摺動自在にされたスライド突起９を有し、スライド突起９に設けた摺動子９ａの位置が内蔵した直線状に延びる抵抗線上で変位することでその抵抗値が増減するような可変抵抗１１を備えて成る板状のリニアセンサ１２ａが用いられている。このリニアセンサ１２ａは、摺動するスライド突起９を平面視で検知胴部７の軸線に重ねると共に、このスライド突起９を検知胴部７の螺旋溝８に係入するようにして、本体ハウジング１３に配置される。螺旋溝８に係入されたスライド突起９は検知胴部７が回転することでその摺動位置が変化するのであり、それに応じてリニアセンサ１２ａの可変抵抗１１の抵抗値が変化するようになる。したがって、図５のように、リニアセンサ１２ａの可変抵抗１１を制御部１５の検知回路１５ａに接続して検知電流を流すと、可変抵抗１１の抵抗値の増減にて変化する検知電流値や検知電圧値を制御部１５にて検出することができ、巻取りドラム４の回転量に基づくスライド突起９の摺動位置、ひいては物干し竿６の昇降位置を電気的に検出できるのであって、物干し竿６の昇降制御を制御部１５にて簡単に行わせることが可能にされている。   And the detection sensor 12 for detecting the raising / lowering position of the hanging basket 6 is arrange | positioned in the position of the main body housing 13 which overlaps with the detection trunk | drum 7 as shown in FIG.1 (b). The detection sensor 12 of this example has a slide protrusion 9 that is linearly slidable, and the position of a slider 9a provided on the slide protrusion 9 is displaced on a built-in linearly extending resistance line. A plate-like linear sensor 12a including a variable resistor 11 whose resistance value increases or decreases is used. The linear sensor 12a has a slide housing 9 that slides on the axis of the detection body 7 in plan view, and that the slide protrusion 9 is engaged with the spiral groove 8 of the detection body 7 so that the main housing 13 Placed in. The sliding position of the slide protrusion 9 engaged with the spiral groove 8 changes as the detection barrel 7 rotates, and the resistance value of the variable resistor 11 of the linear sensor 12a changes accordingly. . Therefore, as shown in FIG. 5, when the variable resistor 11 of the linear sensor 12 a is connected to the detection circuit 15 a of the control unit 15 and a detection current is passed, the detection current value or the detection that changes with the increase or decrease of the resistance value of the variable resistor 11 is detected. The voltage value can be detected by the control unit 15, and the sliding position of the slide protrusion 9 based on the amount of rotation of the winding drum 4, and thus the lifting position of the hanging basket 6 can be electrically detected. 6 can be easily controlled by the control unit 15.

このように本例の昇降物干し装置１では、巻取りドラム４に同軸上に一体に設けて外周に螺旋溝８を刻設した検知胴部７と、螺旋溝８に係入されて巻取りドラム４の回転に応じて摺動位置が決定されるスライド突起９を有すると共にこのスライド突起９の摺動位置を検知して物干し竿６の昇降位置を検出する検知センサ１２とで成る竿位置検出手段１０が設けられているので、巻取りドラム４の回転量を直接スライド突起９の同期した摺動量として抽出できて、このスライド突起９の摺動位置を検知して物干し竿６の昇降位置を検出できる。したがって、たとえば駆動部３内で不具合が生じたりしても巻取りドラム４の回転量との同期性を損なうことのない、巻取りドラム４の回転量（ワイヤ５の巻取り量）と直接的に同期した正確な物干し竿６の昇降位置の検出が確保されており、ひいては制御部１５による正確な物干し竿６の昇降制御が確保されている。しかも、上記物干し竿６の昇降位置を正確に検知する竿位置検出手段１０の構造は、巻取りドラム４に同軸上に設けた検知胴部７の外周に螺旋溝８を刻設すると共に螺旋溝８に係入したスライド突起９を本体部２に直線摺動自在に設置する、すなわち巻取りドラム４の回転運動をスライド突起９の直線運動に変換するといった簡単で且つ省スペース化の確保された構造であり、つまり、竿位置検出手段１０の簡易な構造が確保され、昇降物干し装置１の小型化の促進も可能にされている。   As described above, in the lifting / drying apparatus 1 of this example, the detection drum portion 7 provided coaxially and integrally on the winding drum 4 and having the spiral groove 8 formed on the outer periphery thereof, and the winding drum inserted into the spiral groove 8. 4 has a slide projection 9 whose sliding position is determined in accordance with the rotation of 4 and a detection sensor 12 which detects the sliding position of the slide projection 9 to detect the raising / lowering position of the laundry basket 6. 10 is provided so that the rotation amount of the winding drum 4 can be directly extracted as a synchronized sliding amount of the slide projection 9 and the sliding position of the slide projection 9 is detected to detect the raising / lowering position of the hanging basket 6. it can. Therefore, for example, even if a malfunction occurs in the drive unit 3, the amount of rotation of the winding drum 4 (the amount of winding of the wire 5) does not impair the synchronization with the amount of rotation of the winding drum 4. Thus, accurate detection of the lifting position of the hanging basket 6 is ensured, and as a result, accurate lifting control of the hanging basket 6 by the control unit 15 is ensured. Moreover, the structure of the heel position detecting means 10 for accurately detecting the raising / lowering position of the clothes shed 6 includes a spiral groove 8 engraved on the outer periphery of the detection drum 7 coaxially provided on the winding drum 4 and the spiral groove. The slide protrusion 9 engaged with the slider 8 is installed on the main body 2 so as to be linearly slidable, that is, the rotational movement of the winding drum 4 is converted into the linear movement of the slide protrusion 9, and simple and space saving is ensured. This is a structure, that is, a simple structure of the heel position detecting means 10 is ensured, and it is possible to promote downsizing of the lifting / lowering apparatus 1.

なお、本例では検知センサ１２にはリニアセンサ１２ａを用いているが、検知センサ１２としては、巻取りドラム４の回転に応じた螺旋溝８の規制にて決定されるスライド突起９の摺動位置を検知して物干し竿６の昇降位置が検出可能なものであれば、たとえばフォトインタラプタ等の光学式センサなど、種々のセンサを用いることができる。   In this example, a linear sensor 12 a is used as the detection sensor 12, but as the detection sensor 12, sliding of the slide protrusion 9 determined by the restriction of the spiral groove 8 according to the rotation of the winding drum 4. Various sensors such as an optical sensor such as a photo interrupter can be used as long as the position can be detected and the raising / lowering position of the hanging basket 6 can be detected.

また、本例の巻取りドラム４のワイヤ巻取面２７は傾斜面状に形成されているから、巻取りドラム４が一回転したときのワイヤ５の巻取量は巻取りドラム４の回転が進む毎に徐々に長くなるのであるが、この巻取りドラム４の回転とワイヤ５の巻取量との関係は当該ワイヤ巻取面２７に固有の一定の関係を有するものであり、この一定の関係を考慮してスライド突起９の摺動量とワイヤ５の巻取り量との関係を規定しておけば、物干し竿６の昇降位置の正確な検出が可能であることは言うまでもない。   Further, since the wire winding surface 27 of the winding drum 4 of this example is formed in an inclined surface shape, the winding amount of the wire 5 when the winding drum 4 makes one rotation is the rotation of the winding drum 4. Although the length gradually increases with each advance, the relationship between the rotation of the winding drum 4 and the winding amount of the wire 5 has a certain relationship inherent to the wire winding surface 27. Needless to say, if the relationship between the sliding amount of the slide protrusion 9 and the winding amount of the wire 5 is defined in consideration of the relationship, the raising / lowering position of the hanging basket 6 can be accurately detected.

また、本例では検知胴部７は巻取りドラム４に一体に形成されているが、たとえば一対の巻取りドラム４を連結する連結軸棒１６に一体形成してもよく、これによっても簡易な構造で検知胴部７巻取りドラム４と同軸で一体回転できる。   Further, in this example, the detection body 7 is integrally formed with the winding drum 4. However, for example, it may be formed integrally with a connecting shaft rod 16 that connects the pair of winding drums 4, and this also simplifies. The structure can be rotated integrally with the detection drum 7 winding drum 4 coaxially.
